In the 1970s, a 13-year-old girl was found locked up in a room, strapped to a potty chair Since she had grown up in a world without human speech, researchers studied "Genie's ability to acquire words, grammar, and pronunciation. This type of research is called a. a representative sample a naturalistic observation a single-blind study a case study b. c. d. 12.

It isExplanation / Answer
10.c
Explanation : when a neuron fires it is actually bringing about the concept of action potential. Action potential in either neuron, muscle follows the all or none phenomenon which states that the response of a neuron is independent of the strength of stimulus. Only if the stimulus is more than the threshold potential, a response is given by the neuron(firing of action potential) otherwise no response occurs at all.
11.d
Explanation : Representative sample is a type of study that includes a small number of people representing a larger population. Naturalistic observation is a method of research where study of humans or animals is undertaken in their natural environment (in the above case the girl'room). Single blind studies are used for testing the effectiveness of a drug where the subjects aren't told if they are given test or controlled treatment. Case study is a method of research that studies /records development of a person or population in the present and /or over a period of time. As, in the above example the study of the girl's development in grammar, speech, words would be studied therefore the correct answer is d.
12.b
Explanation : A synapse is a junction between two neurons. The spaces are filled with fluid. Also it's two ends are the synaptic knob of one neuron and the dendrite of the other. Therefore the correct answer is b.
13.b
Explanation : An independent variable in an experiment isn't dependent on any other factor. It is changed/manipulated by the researcher to test if it leads to change in the result. Thus, it is what isn't constant in the experiment. Therefore the correct answer is b.
